Drugged car thief sorry over fatal crash

An Adelaide woman who was high on drugs and driving a stolen car has apologised "from the bottom of my heart" to the family of a man killed when she smashed into his delivery truck.

Sophie Brine also fled the scene of the crash in the city's north in January last year.

Jatinder Singh Brar was killed when the cab of his truck was crushed.

Brine pleaded guilty to causing death by dangerous driving and string of other offences and told the District Court on Monday that nothing she could say would fix what she had done.

"Nothing I do will ever make up for this and I know sorry will never be enough," she told the dead man's family.

"I don't expect you to forgive me but I ask can you please accept my apology from the bottom of my heart."

In a victim impact statement provided to the court, Mr Brar's mother, Kulwinder Kaur said he was her "only hope for the rest of my life".

"Even though I was alone when Jatinder was studying in Australia I had hope he would return to India and he would care for me and be there for me," her statement said.

"But when I heard the news of Jatinder's death my life and my reason to live ended."

The dead man's brother, Beant Kaur, described Mr Brar as a "superhero".

"My brother always took a stand for me. Now life is full of darkness," Mr Kaur said in his statement.

"My brother was my strength. Nobody can replace my brother in my life."

Brine will be sentenced next month
